Sorry, but that effect can also be achieved by the Sun orbiting the earth.
OK - how about this - why does water circle one way in the Northern Hemisphere when going down a drain and circle the other way in the Southern Hemisphere? If the world was stationary - it wouldn't spin at all.
That should prove the Earth's rotation.
Aside from the Simpsons, I don't believe this is well documented.
While technically true, in reality, it's actually a bit of a myth, I believe, as the forces are too weak.
(I saw it on snopes.)
Rotation has a lot more to do with drain design than anything.
That said, their tropical storms DO spin in the opposite direction. (I think!)
"OK - how about this - why does water circle one way in the Northern Hemisphere when going down a drain and circle the other way in the Southern Hemisphere? If the world was stationary - it wouldn't spin at all."
Actually, this falls into the category of an urban legend. Yes, the Earth's rotation does produce something called the Coreolis Effect, but on something as small as the drain in your sink or toilet, the forces are so small that other factors (turbulence, surface friction) will dominate it. So it would be easy for these people to discount this.
But for weather patterns, which are much, much larger, the Coreolis Effect does cause a rotation on winds.
Actually, any Coriolis phenomenon depends on earth's rotation, from water circling a drain to hurricanes (although the whole drain circling thing has been called into question more than once, since the distances covered are so small).
